Pushing yourself in therapy is a good thing. It means, like you said, that you want to get better. You want to work through this. But while pushing yourself is good, not getting guidance from Linda is not. You need to know why you are talking about a certain thing or why you are avoiding it. You also need to know what you are feeling. For example, if you start to talk about when those guys first touched you and you knew you were in trouble and in therapy you start to back off and push Linda away, that is a good point in which to stop and see what you are feeling and why you are pushing away (putting your defenses up). In therapy, I would say to you "what are you feeling right now?". And depending on your answer, I would proceed one way or another.
I would talk to Linda about checking in with you. She needs to know that there is a difference for you between when you feel overwhelmed and need to take a step back and when you need some prompting from her. The only way she will know that is if she asks you what you are feeling.
I'm not sure why Linda is treating your self blame as a different issue. It is connected with what happened to you. I can see that she might mean that blaming yourself is about you and not so much about what the guys did, but even then it is connected. You may want to ask her more about why she wants to look at the self blame separately.
Maybe she does feel overwhelmed by feelings. It could be she has her own issues with it or she uses more of a cognitive type of therapy rather than a feeling based therapy. That would make sense. You may want to ask her that as well. What type of therapy she practices would make a difference in how she approaches your issues.
